Compact Disks - Recordable Drives

ALSO CALLED:
CD-R Drives,
DrivesDEFINITION: CD-R (for compact disc, recordable) is a type of write once, read many (WORM) compact disc (CD) format that allows one-time recording on a disc. The CD-R (as well as the CD-RW) format was introduced by Philips and Sony in their 1988 specification document, the Orange Book. Prior to the release of the Orange Book, CDs had been read-only audio (CD-Digital Audio, described in the Red Book), to be played

After the Orange Book, any user with a CD recorder drive could create their own CDs from their desktop computers.Like regular CDs (all the various formats are based on the original Red Book CD-DA), CD-Rs are composed of a polycarbonate plastic substrate, a thin reflective metal coating, and a protective outer coating. However, in a CD-R, a layer of organic polymer dye between the polycarbonate and metal layers serves as the recording medium. The composition of the dye is permanently transformed by exposure to a Compact Disks - Recordable Drives definition sponsored by SearchStorage.com, powered by WhatIs.com an online computer dictionary
